Effectively Search for set of substrings in a string Javascript

I currently have a string and set of substrings/search strings which I want to effectively search in the given string. This is what I have currently:

const apple = "apple"
const banana = "banana"
const chickoo = "chickoo"
const dates = "dates"
const eggplant = "eggplant"
const default = "default"

let string = "foobar" // This String changes dynamically
if (string.includes(apple)){
    return apple;
} else if (string.includes(banana)) {
    return banana;
} else if (string.includes(chickoo)) {
    return chickoo;
} else if (string.includes(dates)) {
    return dates;
} else if (string.includes(eggplant)) {
    return eggplant;
} else {
    return default;
}

This approach works, however I am looking for a more compact and efficent way of searching for substrings in a given string.

Edit: I am currently using the following way:

const fruits = ["apple", "banana", "chickoo", "dates", "eggplant"];
let string = "foobar" //This is dynamic
for(let fruit in fruits) {
    if(string.includes(fruits[fruit])){
        return fruits[fruit];
    }
}
return "default";

Let me know if there is even more effective way to do this than the above one.

Answer

Using Regex:

function matchFruit(input) {
    const match = input.match(/apple|banana|chickoo|dates|eggplant|default/);
    if(match)
        return match[0];
    return "default";
}

Note

this will only return the first matching fruit in the string. So "foobarapplebanana" will return "apple". If instead you want to return an array of strings, [ "apple", "banana" ], then return match instead of match[0].
